help! broken branch!!

last night i was applying wire to my serissa bonsai when i pulled a branch too far back and it broke, leaving a huge gash down the rest of the branch. it's a fairly large branch and if i left it the way it is it would look hideous. almost immediately i tightly tied the broken piece of the branch back to the rest of the branch with wire just to hold it in place for the time being. i don't know if this will do anything, but i couldn't think of anything else to do. if anyone could offer any sort of advice, it would be MUCH appreciated. it would be great if i could salvage this poor branch! help!

Re: help! broken branch!!

Jimmy, first let me say I am a novice.... take my advise as such. It sounds to me like the branch seperated. Is this from the trunk or part of the way in from the trunk? Either way it seems like you are going to have to treat this like a graft. Keep the broken parts together, if you can get some cut paste use it to seal the wound. It will take awhile to heal and probable be a weak spot. I have read where raffia is wrapped around a limb before bending to act as a brace if you will.
Good luck and hopefully you will get more advise from more advanced individuals.

The only thing I can add is that you should make sure the cambium meets up on the two sections exeactly like they were before and then seal it good to keep it from drying out. With any luck the sections will grow together in a year or two.

Re: help! broken branch!!

Jimmy,


I did the same thing about a week ago on my juniper. In my case the branch was still connected with a HUGE crack on the branch. I used "Fun Dap" and wrapped this around the wound. It seems to be working you might wanna try it. In case your wondering.. Fun Dap is a putty used to put posters and pictures on the walls... Check your local Walmart..

good luck with that branch!



Jeff...

Re: help! broken branch!!

Okay i hope the picture i attached and my lengthy explaination will make some sense of what happened... First of all, as soon as i got home that day, the leaves were shriveled and a bunch fell off... I left the broken branch tightly attached to the rest of the tree using wire and went looking around in my mom's gardening stuff for some sort of sealant and i found a tube of something called 'thomson's organic sealer' that she used on one of her plants in the house. So anyway i put a dab of the stuff on my finger and spread it on to the broken part of the branches and held it in place for about half an hour or so, just to be sure it stuck. After a couple days all the leaves had fallen off the branch that was seperate from the tree but the leaves of the branch that were still attached to the rest of the tree were as healthy as they were before. I left it be just to see if maybe new leaves would grow back.. But then last night i went to check on my trees and the branch had fallen off! There was no point in re-applying the sealer since the wounds had already dried up. So aaanyway, all thats left of it is a big ugly scar on the branch that remained in tact. Luckily, the leaves are still growing and even new shoots have started growing off the branch so i dont think it's in too much danger.. It's just a matter of appearance. I attached a photo which may help explain what went on... (sorry for the poor illustrations)

(1)the location of the branch on the tree.
(2)the direction in which i wanted to bend the branch.
(3)the trunk in relation to the branches.
(4)where the branches split.
(5)what the branch looks like now.

The reason for the illustration instead of an actual photo is due to my lack of a digital camera/ scanner.

Thanks everyone for your help =]

Why branches break - what to do w/ a broken branch

In teaching beginner bonsai classes we practice wiring and bending garden material and learn how, where and why branches break.

Branches tend to break where they are weakest or under the most stress:
  • at the outside radius of bends
  • At or near branch forks, where the wood is less pliable
  • At the the site of wounds
Refering to the diagram below, one thing to keep in mind when bending branches is that the branch rarely breaks right at the point where it is supported by wire (C) or where it is compressed, even strongly (A), but rather where it is under tension but unsupported by wire (points like B) or the break illustrated.

So if you avoid trying to create bends at areas where you have wounds or forks, and wire the branch with the intention to protect the outside radius of the curve with a wire, then grasp the branch with the thumbs on the interior of the curve and push it into the wire, it will be less likely to break.

Another step you can take is to "exercise the branch" prior to wiring by bending it back and forth. This breaks up the cellular structure of the branch. Don't water the tree in the 24 hour period prior to bending. With the cells full of water (turgid) they put up more resistance to bending.

WHEN A BRANCH BREAKS

Don't try to force it back too much or you may break the cambium on the opposite side and really stuff it up. Instead try and ease it back gently. Then immobilize the branch by securing it to another branch or making a splint from a chopstick tied across the wound.

Dab the wound edges and completely seal the area with a wound sealant; you can use most anything from grafting pastes to latex sealants. The Masakuni sealant or Callusmate over at TreeBay Bonsai Tools & Supplies
work fine. I wouldn't use cut paste for this because it's too hard to apply at a weak joint.

Hope this helps in the future.
